Description of the embodiments

The utility model is described in more detail below with reference to the accompanying drawings. An improved structure of oven door hinge, which is characterized in that: the oven comprises a main body 2 fixed on an oven door 1 and a trigger 3 movably hinged and installed on the main body 2, wherein the trigger 3 is hung and buckled on a connecting plate 5 in a box body 4 to be fixed, so that the oven door 1 is opened and closed, the section of the main body 2 is in an open groove shape, a tension spring 6 is installed in the open groove, one end of the tension spring 6 is fixed with the main body 2, the other end of the tension spring is hinged with the trigger 3 through a pull arm 7, the tension spring 6 generates tension force to pull the trigger 3 towards the closing direction all the time through the pull arm 7, and door closing power is generated;

the trigger 3 is provided with a mounting hole 31, a safety buckle 8 is mounted in the mounting hole 31 through a pin 32, the safety buckle 8 is bent into an n shape by stamping a metal plate, the safety buckle 8 is mounted outside the trigger 3 through the pin 32 in a clamping manner, the trigger 3 is provided with a locking groove 321, the safety buckle 8 is buckled into the locking groove 321, a limit area 33 is formed between the side wall of the safety buckle 8 and the side wall of the locking groove 321, and the limit area 33 is clamped on a connecting plate 5 in the box body 4 and fixed; the side wall of the safety catch 8 is provided with a guide groove 81, the pin 32 is inserted into the guide groove 81, and the safety catch 8 slides up and down along the guide groove 81, so that the safety catch 8 is driven to be buckled with or separated from the locking groove 321.

The safety catch 8 comprises a connecting plate part 82 and clamping plate parts 83 at two sides of the connecting plate part 82, and the connecting plate part 82 is buckled into the locking groove 321 for fixation.

The connecting plate 82 and the clamping plate 83 on both sides are integrally punched from a metal plate.

The guide grooves 81 are arranged in a long waist shape and vertically distributed on the clamping plate portion 83.

The front end and the rear end of the pin 32 are distributed and protrude out of the outer surface of the guide groove 81, and the end face of the pin 32 is also provided with a blocking head 34 which is covered outside the guide groove 81.

The locking groove 321 is an inner groove provided on the trigger 3, and the width of the locking groove 321 is larger than that of the connecting plate portion 82.

Working principle: in the scheme, a safety catch is arranged on the trigger and can swing and slide up and down and is arranged on the trigger. When the oven door and the oven body are required to be installed, the safety catch is opened, and the trigger is inclined upwards, so that the trigger can be obliquely inserted into the installation groove on the connecting plate. The locking groove on the trigger is used for hooking in the mounting groove. And then closing the safety buckle, and fastening the safety buckle in a locking groove on the trigger by utilizing a connecting plate part on the safety buckle. Therefore, a limit area is formed between the safety catch and the locking groove, and the locking groove is clamped on the connecting plate in the oven and fixed with the connecting plate. Therefore, the relative position between the trigger and the connecting plate of the oven door can not be changed in the opening and closing process, and loosening can not occur, so that the oven can work stably for a long time. When the user needs to detach the oven door, the safety catch is lifted upwards, so that the safety catch upwards slides along the pin through the guide groove, and the connecting plate part of the safety catch is separated from the locking groove, so that the safety catch can be separated from the connecting plate through rotating, and the effect of detaching the oven door is realized.

Wherein: as shown in fig. 6 and 7, in order to facilitate the up-and-down sliding of the safety catch, the safety catch is snapped or separated from the locking groove, and the guiding groove 81 in this case is provided in a long waist shape and vertically distributed on the clamping plate 83. And only one mounting hole 31 with smaller perforation area is arranged on the trigger for mounting the pin. Conventionally, the trigger and the safety catch in the production scheme are all formed by punching through a punching machine. The requirements for the performance of the punching machine mainly comprise the thickness of the plate, the hardness of the plate and the punching area. In contrast, the trigger has a plate thickness that is much greater than the plate thickness of the safety catch. The punching area of the guide slot 81 is larger, so that the punching on the trigger has higher requirements on the performance of the punching machine, and the punching on the safety button has lower requirements on the performance of the punching machine because the plate is relatively thinner and the hardness is relatively lower.
